A benign esophageal stricture, or peptic stricture, [1] is a narrowing or tightening of the esophagus that causes swallowing difficulties. Signs and symptoms.
An esophageal food bolus obstruction is a medical emergency caused by the obstruction of the esophagus by an ingested foreign body.. It is usually associated with diseases that may narrow the lumen of the esophagus, such as eosinophilic esophagitis, Schatzki rings, peptic strictures, webs, or cancers of the esophagus; rarely it can be seen in disorders of the movement of the esophagus, such as ...
Other strictures may include esophageal webs (which can also be congenital) and damage to the esophagus by radiotherapy, corrosive ingestion, or eosinophilic esophagitis. A Schatzki ring is fibrosis at the gastroesophageal junction. Strictures may also develop in chronic anemia, and Plummer-Vinson syndrome. [5]
Esophageal strictures, when scar tissue from acid reflux, infections or surgery causes narrowing. Neurological conditions, including Parkinson's disease, stroke, multiple sclerosis or amyotrophic ...
Esophageal stricture can also be due to other causes, such as acid reflux from Zollinger–Ellison syndrome, trauma from a nasogastric tube placement, and chronic acid exposure in patients with poor esophageal motility from scleroderma. Other non-acid related causes of peptic strictures include infectious esophagitis, ingestion of chemical ...
Complications of the disorder include stricture of the esophagus, which can lead to food bolus obstruction, and weight loss. Treatment of lymphocytic esophagitis includes medications meant to target the esophagus topically, such as budesonide, but also procedures to deal with complications, such as esophageal dilation.
The narrowing is caused by a ring of mucosal tissue (which lines the esophagus) or muscular tissue. [1] A Schatzki ring is a specific type of "esophageal ring", and Schatzki rings are further subdivided into those above the esophagus/stomach junction (A rings), [2] and those found at the squamocolumnar junction in the lower esophagus (B rings ...
Strictures or narrowings in the esophagus may also be seen, typically in the upper esophagus. [ 5 ] [ 6 ] As esophageal intramucosal pseudodiverticulosis is also associated with motility disturbances of the esophagus, manometry testing of esophageal pressures may provide information to assist in the diagnosis.
